This Small Business Innovation Research Phase I research project will develop and employ an innovative signal amplification methodology to create highly sensitive polymer sensors that can detect mold in residential and workplace settings. One method is to detect the airborne microbial volatile organic compounds (MVOC) released by growing mold. However, to be valuable any technology needs to be highly sensitive to the MVOC compounds, provide real time results, portable and inexpensive. The results of the proposed research will lead to highly sensitive sensors that can be incorporated into a handheld instrument which will regularly screen suspect areas to provide early detection and point of source mold detection in areas where mold may be present but not seen, create building histories, provide understanding of the relationship between mold and health, and promote standards relating to the levels of MVOC in workplaces and other buildingsCurrently mold is primarily detected through human observation - sight and smell ? however, by the time mold is detected through human observation, it has already been growing for some time in hidden or inaccessible areas, and may have caused adverse health problems and significant property damage. The proposed research will enhance the science of polymer based sensors through developing and proving a new signal amplification strategy. This same strategy can be used across many different polymer types and detection problems to enable trace detection of compounds in other applications such as security explosives) and industrial safety (toxic industrial chemicals).This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

这个小型企业创新研究第一阶段的研究项目将开发和采用创新的信号放大方法，以创建高灵敏度的聚合物传感器，可以检测住宅和工作场所的霉菌。一种方法是检测空气中的微生物挥发性有机化合物（MVOC）释放的增长模具。然而，任何有价值的技术都需要对MVOC化合物高度敏感，提供真实的时间结果，便携且便宜。拟议研究的结果将导致高度敏感的传感器，可以纳入手持仪器，该仪器将定期筛选可疑区域，以在可能存在霉菌但未看到的区域提供早期检测和源霉菌检测点，创建建筑历史，提供对霉菌与健康之间关系的理解，并促进与工作场所和其他建筑物中MVOC水平相关的标准目前，霉菌主要通过人类观察-视觉和嗅觉来检测？不过，当人类观察发现霉菌时，它已在隐蔽或人迹罕至的地方生长了一段时间，可能对健康造成不良影响，并造成重大财产损失。拟议的研究将通过开发和证明一种新的信号放大策略来增强聚合物传感器的科学。同样的策略可以用于许多不同的聚合物类型和检测问题，以实现在其他应用中对化合物的痕量检测，例如安全爆炸物和工业安全（有毒工业化学品）。该奖项由2009年美国复苏和再投资法案（公法111-5）资助。
